The seminar meets on Wednesday March 7th at 11:00 in the Institute of
Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building.
Program: Adam Bartoš — Compactifiable classes and Borel complexity up
to the equivalence
We discuss the notion of compact composition of a class of metrizable
compacta, and a general question of compactifiability of a given class.
This is connected to the Borel complexity of subsets of the hyperspace
of all metrizable compacta, up to the equivalence of classes.
